The Messenger Must Deliver
[5:67] O you messenger, deliver what is revealed to you from your Lord – until you do, you have not delivered His message – and GOD will protect you from the people. GOD does not guide the disbelieving people.
[5:68] Say, “O people of the scripture, you have no basis until you uphold the Torah, and the Gospel, and what is sent down to you herein from your Lord.” For sure, these revelations from your Lord will cause many of them to plunge deeper into transgression and disbelief. Therefore, do not feel sorry for the disbelieving people.
Is it possible for the messenger to not deliver the entire message?
[5:101] O you who believe, do not ask about matters which, if revealed to you prematurely, would hurt you. If you ask about them in light of the Quran, they will become obvious to you. GOD has deliberately overlooked them. GOD is Forgiver, Clement.
[20:114] Most Exalted is GOD, the only true King. Do not rush into uttering the Quran before it is revealed to you, and say, “My Lord, increase my knowledge.”
